This method is to be used for testing the flow resistance of balancing valves with presetting facility. A method for calculation of the 95% interval of prediction on the flow resistance for a number of equal valves is described.

The aim of the BASREC standardisation project was to establish contacts between relevant national organisations in the Baltic Sea Region and Technical Committees within CEN to prepare possible contributions to ongoing activities on solid biofuel standards and further to investigate the needs and possibilities for common test methods and rules regarding biofuels and biofuel machinery and systems in the area.

An important step in moving toward international standardization is to come to a consensus about what exactly is proper and adequate function in a negative-pressure isolation room. In this report we examine current and best practice in design and performance testing of negative pressure isolation rooms in Nordic hospitals.

Sustainable development requires an environmentally sound, cost effective and socially acceptable management of municipal and industrial waste. Landfilling of untreated municipal solid waste (MSW) is known to lead to emissions of leachate and landfill gas, above all methane, which contributes to the greenhouse effect.

The objective of this project is to investigate if leachate from Norwegian landfills affect the reproductive system in fish, similar to what is found in Lake Molnbyggen in Sweden, and to evaluate and, if necessary, to adapt existing tests for biological characterisation of leachate to see whether they are suitable for detecting such disorders.

Facade cladding of marble has, in several cases, suffered from problems with bowing panels that also loose strength. When not exchanged or repaired there is an obvious risk of panels falling down with time. The project objectives are to develop a laboratory test method for the detection of marble with a potential risk of bowing and to develop a field site investigation method.

This NORDTEST method is intended for exposing materials and components used in the building envelope to UV light, heat, water and frost. The method seeks to simulate the natural climatic strains. Its objective is to concentrate the individual climatic factors so that, in total, they produce a cycle of strains giving degradation results similar to natural exposure but in a much shorter period of time.

This test method covers the determination of the retention curve and the pore size distribution of porous building materials and soils using a combination of pressure plate, pressure membrane and/or sand box apparatuses.
